Let the score of Bill = Bthe score of John = Jthe score of Sue = S

B= J+20B= S/2

B+J+S=180=> B+ B-20 + 2B= 180=> 4B = 200=> B =50

Seeing a question like this should always trigger your algebraic brain cells

J=B-20B=J+20B=0.5*SS=2B

B+J+S=180

Now try using only ONE variable, in our case we will use B.

B+B-20+2B=180Simplify to get all variables on one side and all numbers on the other side4B=200B=50
